3) Assume that the readings at freezing on a batch of thermometers are approximately Normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the proportion of thermometers with a reading greater than -3.205°C. Round to 4 decimal points

4) Assume that the readings at freezing on a batch of thermometers are approximately Normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the proportion of thermometers with a reading greater than 1.674°C. Round to 4 decimal points

5) Assume that the readings at freezing on a batch of thermometers are approximately Normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the proportion of thermometers with a reading between -1.864°C and -1.544°C. Round to 4 decimal points

6) Assume that the readings at freezing on a batch of thermometers are approximately Normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the proportion of thermometers with a reading outside of the interval -1.228°C and 1.995°C. Round to 4 decimal points

7) Assume that the readings at freezing on a batch of thermometers are approximately Normally distributed with a mean of 0°C and a standard deviation of 1.00°C. Find the proportion of thermometers with a reading between -0.677°C and 0.955°C. Round to 4 decimal points.

8) For a Normal distribution with μ=9.2μ=9.2 and σ=0.8σ=0.8.

9) What proportion of observations have values less than. Round to 4 decimal points

10) For a Normal distribution with μ=3.8μ=3.8 and σ=0.8σ=0.8, what proportion of observations have values greater than 4? Round to 4 decimal points
